What we know of the facts so far (not a lot) seems to point at two possibilities. The vagueness of the reported accusation may mean that the real reason is being kept hidden - it might be a totally stellar chap or chapess lined up to step in and hit the ground running. Or at least a relative of a person with influence in the organisation. But the business about "does not understand the organisation and what it's about" does look rather like a bierkeller putsch by DEAFASS or at least those who are wholly focussed on a backward looking folk music. I say this with all due care since I am a staunch 1954 definitioner and a firm believe that the archiving and preservation function of the EFDSS (or at least the English Song Society) is its most important aspect, but an archive that is not used and where treasures may be lost to physical corruption for lack of funds can be as much a hindrance as a help.
